SB!!! 1 0f 2 .DISIOSABLE TRASH RECEPTACLE This invention relates to an improvement in disposable trash receptacles and deals particularly with a body made of paperboard into which trash and like may be disposited, and which may be disposed of when it become filled.

BACKGROUND OF THE INVENTION Trash receptacles usually comprise metal containers of one type or another into which trash may be inserted. Some such receptacles are generally cylindrical or somewhat tapered bodies of heavy wire netting or the like having open tops. Others comprise rectangular metal containers having hingedly connected doors at their upper ends to which the trash may be inserted. While such metal receptacles serve their intended purpose very well, certain difficulties are experienced. At intervals, the receptacles must be lifted up and emptied into a truck or trailer for conveyance to a point of dis posal. In the operation, the containers are apt to be come dented, and the paint chipped. As a result, while they are actually durable, they require maintainance. Furthermore, such receptacles are normally heavy and difficult to handle, and are quite costly to purchase and maintain.

SUMMARY OF THE DISCLOSURE The present invention resides in the provision of a disposable trash receptacle made of paperboard such as corrugated paperboard or the like. These trash receptacles have one or more openings in the upper end into which the trash may be inserted. Rather than to provide merely ordinarly rectangular box-like body, the side walls are formed entirely of isosceles triangle panels. As a result, the receptacles are extremely decorative in appearance, and add to the appearance of the environment rather than to detract from it. The purpose of the arrangement is to produce the receptacles at sufficiently low cost that they may be disposed of and merely replaced at suitable intervals.

The object of the present invention is provide a trash receptacle, the side walls of which are made by 16 areas which are isosceles triangular in shape. Such areas include two sides of equal length and a third side. The panel structure includes an upper series of intermediate triangular portions having their third sides on a common plane to form the top of the receptacle. Four diamond shaped areas are provided, the diamond shaped portions being divided into upper triangular portions and lower triangular portions along their third sides. The equal length edges of the upper portions of the diamond shaped portions are hingedly connected to the equal length sides of the intermediate triangles. Four lower intermediate isosceles triangular portions are provided and arranged in rectangular relation with their third edges on a common plane parallel to the common plane of the intermediate triangular panels between the upper portions of the diamond shaped areas. These lower isosceles intermediate triangular portions are hingedly connected to the lower triangular portions of the diamond shaped portions. Closure flaps are hingedly connected to the third sides of the lower intermediate triangular panels which may be folded and secured together to form the bottom of the receptacle.

These and other objects and novel features of the present invention will be more clearly and fully set forth in the following specification and claims.

DESCRIPTION OF THE IPREFERRED EMBODIMENTS The container which is indicated in general by the letter A is of somewhat unusual shape. The upper and lower edges of the container are rectangular. There is also an area intermediate the top and bottom edges which is also rectangular, but the comers of this rectangular area are at a 45 angle to the top and bottom edges. The side walls are formed entirely of isoscles triangles having two equal sides and a third side connecting the ends of the equal length sides.

As indicated in FIG. 3 of the drawings, the blank includes four isoscles triangular panels which have their third sides 14 hingedly connected to reinforcing flaps or flanges 15. Four diamond shaped portions indicated in general by the numerals 16, 1'7, 18 and 19 are divided into upper and lower isosceles triangular portions along a fold line 20. The fold line 20 divides the diamond shape portions into upper isoscels triangle portions 21, 22, 23, 24 and lower isosceles triangular portions 25, 26, 27 and 29. One of the equal length sides of the triangular portion 21. is connected to the panel 10 along a fold line 30. The triangular portion 22 is connected to the panels 10 and 11 along fold lines 31 and 32. The triangular portion 23 is connected to the panels 11 and 12 along fold lines 33 and 34. The triangular portion 24 is connected to the panels 12 and 13 along fold lines 35 and 36. Thus the portion between the fold line 14 and the fold line 20 is entirely made up of triangular areas, the intermediate panels l0, l1, l2 and 13 extending with apices pointed downwardly, and the triangular portions 21, 22, 23, and 24 being arranged with their apices directed upwardly.

The blank is also provided with lower intermediate panels 39, 40, 41 and 42 the apices of the isosceles triangles extending to the apices of the upper intermediate panels 10, 11, 12 and 13. The equal length sides of the intermediate panel 39 are connected to the lower triangular portions 25 and 26 along fold lines 43 and 44. The sides of the the triangular panel are con nected to the triangular portions 26 and 27 along fold lines 45 and 46. The sides of the triangular panel 41 are connected to the triangular portions 18 and 19 along fold lines 47 and 49. Similarly, the equal length sides of the intermediate triangle panel 42 are connected along a fold line 50 to the panel portion 19.

In order to hold the blank in rectangular relation, one end of the blank is provided with a right angle triangular overlapping area 51 hingedly connected at 52 to the panel 13 and terminating at the fold line 20. A second right triangular portion 53 is connected to the intermediate triangular panel 42 along a fold line 54. Slots 55 and 56 interupt the fold lines 52 and 54 respectively. Locking tongues 57 and 59 project from the edges of the triangular portions 21 and 25 which form the other end of the blank. These locking tongues 57 and 59 are designed for engagement in the slots 55 and 56 respectively to lock the panel in right angular relation.

Closure flaps 60 are hingedly connected to the third sides of the intermediate panels 39, 40, 41 and 42 respectively along a common line of fold 61. These closure flaps 60 are folded into overlapping relation to form the receptacle bottom.

The container cover is shown in blank form in FIG. 4 of the drawings. The cover includes a cover panel 62 having an aperture 63 therein through which the trash may be inserted. Side flanges 64 are hingedly connected to opposite sides of the panel 62 along fold lines 65. The flanges 64 are preferably of trapezoidal form with the ends of the flanges connected along fold lines 66 to to corner flaps 67. The remaining opposite sides of the cover panel 62 are hingedly connected along fold lines 69 to side flanges 70. The opposite sides of the flanges 70 are connected along double score lines 71 to liner flanges'72 which are provided with projections 73 designed to lock into slots 74 adjoining the fold lines 69 in the cover panel 62. Locking tongues 75 are hinged to the center portions of the flanges 72. When the container is set up, the flanges hinged to the upper end of the recetacle are folded outwardly and downwardly and the ocking tongues 75 engage beneath these flanges 15 to prevent the removal of the cover.

The structure shown in FIGS. 5, 6 and 7 of the drawings is identical to that illustrated in the previous drawings with the exception of the portion above the fold line 14. As indicated in FIG. 7 of the drawings, a top panel 80 is hingedly secured to the panel 13 along the fold line 14, and includes an aperture 81 into which trash may be directed. An isosceles triangular portion 82 is hingedly connected to the intermediate panel 12 along the fold line 14, and is connected along double fold lines 83 to right triangular portions 84, one of which is connected to the panel 80 along the double fold line 85. The other edge of the right triangular portion 84 is connected along the double fold lines 86 to a top panel 87 having an aperture 89 therein. The triangular panel 10 is connected along the fold line 14 to an isosceles triangular portion 90 connected along double fold lines 91 to a right triangular portion 92 connected to the panel 87 along the double fold lines 93. A second right triangular portion 94 is connected to the isosceles triangular portion 90 along a double fold line 95, and is connected to an overlapping flap 96 along double fold lines 97. The flap portion 96 is provided with a cut out 99 which is designed to underlie the panel 80 and to coincide with the opening 81. The top panel 80 is connected along a fold line 100 to a flap 101 which is secured to the under surface of the panel 87.

In forming the top of the container shown in FIGS.

and 87 respectively. The construction illustrated in FIGS. 5, 6 and 7 differs from that disclosed in FIGS. 1 to 4 inclusive in that it has an integral top portion formed to two apertured panels rather than a single removable top cover member B such as is illustrated in FIGS. 1 and 2 of the drawings.
